Oh, WOW!
My bedroom is upstairs and I leave the baseboard heat in there off most of the time. There is a pellet stove there and, when it gets really cold outside, it is on. Like today, for example! So: it is cool in the bedroom. I have an electric blanket that I've used for years to 'preheat' my bed before jumping in. But I felt it wasn't quite doing the job. Looking for a mattress pad heater, after 'looking' at others, I landed on this one. When I go in to do my evening ablutions, I turn on both the blanket (it has a 'preheat' setting) and the mattress pad, usually to 6 or 7. By the time I am ready to jump in bed, it is TOASTY in there! The title of this review comes from what I said the first time I crawled in! Oh WOW! OMG would be fitting as well! I have never left it on all night: I preheat the bed, then turn it off, and leaving the blanket on the lowest setting or, depending on the room temperature, turn it off as well. Controls are easy to figure out. Seems to be a well-built unit. Lying on it adds another layer to my padded mattress which also has a mattress pad on it! Double comfort! I am pretty sensitive and, opposed to other post on this, I do NOT feel the heating coils. It might be because I use thick flannel sheets, but I don't think I would feel them even with regular sheets. This pad is doing exactly what I bought it for!

Good purchase
It is SO nice to get in to a warm bed on a cold night. Not since I owned a heated water bed has bedtime been so pleasant, I only need the low heat setting. I like to start the heater a half hour or so before bedtime. The controller allows me to have the heat turn off during the night, after I have the bed up to my normal temp.

Cozy, customizable warmth for chilly nights
I love this mattress pad for nights when I’m chilled or want to climb into a warm bed. The king-sized version is great because each side has its own controller, so both sleepers can adjust the temperature to their preference. It’s perfect for winter or after a long, cold day. I usually can’t sleep through the night with it on because it gets quite warm, but the automatic shut-off and timer options are convenient. The only downside for me is feeling the wires under my body — I’m sensitive to textures, so I gave it 4 stars, wondering if the wires could be thinner or smaller. Even so, I would buy it again for the warmth and comfort it provides.

Roasty Toasty - I'll never be cold again
This thing is amazeballs. It works too well- this is day 2 of having it on my bed and my husband and I both feel like rotisserie chickens after having it on for a few mins. We haven't found the sweet spot yet for what level to put it on. We've went hard and started at level 10... We are in fact not in need of heat that intense. We live in North Carolina. 😂 I am not disappointed with it working too well, I hate being cold and I bought this because I've been huddled under a heated throw blanket since this particularly harsh winter started. Husband didn't want to like it but he loved it immediately. I can crank my side up to hellfire hit and his side stays at whatever temp he wants. Annnnd since it helps ease his diagnosed back issues, I can get my FSA to reimburse me. Huge win. 10/10 would buy again.

Best purchase this year
In the past month I have bought FIVE of these so far - one for me and four as gifts for my friends! They can't stop thanking me. An hour before bedtime I set it on number 4. You can pick a setting depending on how cold you might feel. It has an auto shutoff feature and can heat the bed for up to 8 hours. The heated mattress pad has the option to heat the whole bed or just one side of the bed if that's all you need. This is my favorite purchase in years - I don't know how I never owned one of these before. I chose SERTA because I trust the brand - they've been in the mattress world for years. Go ahead - get yourself this winter treat and go to bed smiling :)

Warm luxury.
Like an electric blanket in reverse. Warms the mattress nicely. You stay nicely warmed with just a light top cover over you. The addition of a "on-off" light would be nice.

I was searching for a high end matress protector (protect from liquids, etc) but also wanted a full bed heating pad. After reading about how some matress protectors conflict with full bed heating pads I thought this would be perfect. And it is. Top quality matress protector with a full bed heating pad built in. Easy to use controller with long cords (to the outlet and the wired controller to the matress protector). Couldn't be better. When I ordered I noticed a few reviews that had issues with warranty but based on my experience so far as long as you take care of it and follow the washing instructions etc I don't forsee any issues. And yes, it's even machine washable. Not the cheapest product on the market but honestly it's the best and worth spending the $$$ for a more comfortable sleep.
